About the Vail Amp and In-Wall Speaker Package

In-wall Echo Dot amplifier and in-wall speakers

The innovative Vail Amp from Vanguard Dynamics lets you turn a wired multi-room audio system into a modern "smart" system with convenient voice control, using your Amazon Echo Dot (not included) as the music source. Its 30-watt x 2 amplifier powers the included pair of Polk Audio RC65i speakers, for way better sound than the Dot's internal speaker can produce.

Its 30-watt x 2 amplifier powers the included pair of Polk Audio RC65i speakers, for way better sound than the Dot's internal speaker can produce.

Multi-room audio and voice control

You can use multiple Vail Amps (and Echo Dots) to create a whole-home system with voice control. You can tell Alexa to play different music in each room, streaming Alexa-friendly services like Spotify and Amazon Music Unlimited via Wi-Fi®. With an Echo Dot in each room, you get manual push-button control and voice control over the system, without having to run a lot of wire or infrared repeaters. You can even go a little bit old-school and use it as an intercom system.

The Vail Amp mounts your Dot in an attractive in-wall dock, where it doubles as a "local" in-wall volume control for that room. You can make the installation match your decor with the included paintable trim plate. An included wall plate module contains input connections for a local source like a TV, and an output for adding a powered subwoofer.

Amplifier Section

Vail Amp: The Vail Amp turns the Amazon Echo Dot (2nd generation) into an in-wall high-performance audio source. The small fully contained amplified assembly firmly holds the Echo Dot (2nd gen) in an attractive wall dock that allows for accurate voice intelligibility and convenient light switch level access to the Dot's surface controls. Its high-power amplifier can be connected to up to two pairs of any in-ceiling, in-wall, or cabinet speakers. The Vail Amp becomes your in-wall volume control keypad, voice control, and streaming music source.

High-Performance Digital Amplifier: The Vail Amp is equipped with a 30 watt x 2 channel Class D amplifier capable of powering two pair of 8-ohm loudspeakers or one pair of 4-ohm loudspeakers. There is a switch on the front of the Vail Amp that can be set to 8- or 4-ohm. The Vail Amp utilizes four screw-down terminals that will accept 16- or 18-AWG bare wire (will not accept pin-connectors, spade-lugs, or banana plugs).

Analog Inputs & Sub Out: The Vail Amp features a male stereo minijack (3.5mm) connector which plugs into your Echo Dot (2nd generation). The included Wall Plate has an stereo RCA input and mono-RCA subwoofer output. The stereo RCA input allows you to connect a secondary audio source to the Vail Amp (your second audio source must have a variable audio output; the Vail Amp was not intended for audio sources with fixed audio outputs). The subwoofer output provides a convenient location to connect any powered subwoofer for added bass.

Note: A 6.5' CAT-5 cable is provided that plugs in between the Vail Amp and the Wall Plate in order to transmit the audio from the analog inputs and sub output between the two in-wall components.

In-Wall Installation: Both the the Vail Amp and included Wall Plate will require you to cutout a hole in your wall (mounting templates are provided). The Vail Amp requires a circular cutout with a diameter of 4.5" and mounting depth of 3.25". The Wall Plate will require a rectangular cutout measuring 1.25" (w) x 2.8125" (h) x 2.25" (d), and mounts to a single-gain box (sold separately). The outer dimensions of the Vail Amp with its paintable trim cover installed measures 5.3125" (w) x 5.3125" (h) x 0.25" (d). The outer dimensions of the Wall Plate measures 2.8125" (w) x 4.5625" (h) x 0.6875" (w).

Note: When mounting the Vail Amp and Wall Plate, keep in mind the length of the included cables. The power/ground cable and CAT-5 cable that run through the wall can be extended up to 300' to mount the Vail Amp and Wall Plate further apart. The 24V power supply has a fixed 39" DC cord, so you'll need to make sure the Wall Plate is mounted near an electrical outlet.

24V Power Supply: The Vail Amp comes with a 24V power supply. The power supply plugs into an AC wall outlet or surge protector (sold separately) and features an attached 39" DC cord that will plug into the "Power" port on front of the Wall Plate. The included 6.5' power/ground harness runs through the wall and plugs in between the Vail Amp and Wall Plate to supply power to the high-performance digital amplifier and your connected Echo Dot (2nd gen). The Vail Amp features a male microUSB connector that plugs into your Echo Dot (2nd gen) for power.

In-Wall Speakers

Woofers: The Polk Audio RC65i speakers features a 6-1/2" Dynamic Balance, mineral-filled polypropylene woofer for clean midrange and deep, accurate bass. For a smoother response and improved durability, each woofer uses a rubber surround.

Tweeters: Each RC65i uses a 3/4" Dynamic Balance, metalized soft dome tweeter in a ball-and-socket swivel mount. The aimable tweeters give you direct high-frequency control, resulting in excellent imaging even for off-axis listening positions.

Dynamic Balance Technology: Dynamic Balance drivers are used for wide, smooth response and low distortion.

Infinite Baffle Tuning: Infinite Baffle Tuning uses the virtual enclosure of in-wall space for superior bass response.

Moisture-resistant: Durable, moisture-resistant materials allow you to install the speakers in bathrooms, kitchens, even under the eaves of an enclosed porch. (The speaker is not recommended for exposed outdoor use.)

Installation: The RC65i in-wall speakers require a cutout 7.3125" wide and 10.75" high with a mounting depth of 2.407". Once the holes are cut, each speaker can be dropped in and the Rotating Cams can be tightened, allowing you to secure each speaker to the drywall without any extra assembly (the Rotating Cams protrude out 0.625" from the cutout opening). If you will not be mounting these speakers in drywall, make sure the wall or ceiling material can safely support the weight of the speakers before installation; each speaker weighs approximately 3.75 pounds.

Paintable: The grille and flange can be painted, allowing these speakers to match any decor.

Frequency Response:

  • Overall: 32 Hz-20 kHz
  • -3 dB Limit: 60 Hz-20 kHz
